TS-Optics 2" CCD Reductor 0.67x for RC y aplanador de F/8

El reductor CCD de 2 "reduce la longitud focal de los telescopios con el factor 0.67x, permitiendo tiempos de exposición significativamente más cortos.

♦ El reductor focal es perfectamente adecuado para el telescopio RC. También funciona bien con los telescopios Celestron EHD o Meade ACF o con refractores hasta la relación focal F / 9
♦ El campo de imagen de las cámaras DSLR hasta formato APS-C está iluminado: iluminación total de hasta 29 mm
♦ Fácil conexión al telescopio a través de un cañón de 2 "
♦ La distancia de trabajo óptima desde la rosca M48x0.75 hasta el sensor de la cámara es de 85 mm: espacio suficiente para accesorios como el guiador fuera del eje o la rueda del filtro
♦ Rosca de filtro de 2 "en el lado del telescopio

TS Optics CCD telecompressor for Ritchey-Chrétien and other F/18 to F/8 telescopes

The TS telecompressor CCD47 was developed for reducing the focal length of RC (Ritchey-Chrétien) telescopes. Practical tests have also shown an excellent suitability for all telescopes with flat field, like apochromats with built-in corrector lens, Celestron EHD or Meade ACF telescopes, thus the most flat-field telescopes. We especially recommend the compressor for the GSO / TS Optics / AstroTec Ritchey-Chrétien telescopes.

The features of the CCD47 telecompressor:

♦ Barrel size is 2" - easy connection to all focusers with 2" receptacle
♦ With thread for 2" filters at the telescope side
♦ Camer aconnection via M48x0.75 thread
♦ Optimal working distance from the connection thread: 85 mm to the camera sensor. Between 70-90 mm, the results are very good.
♦ Reduction by 0.67x - an RC with F/8 changes to fast f/5.3. A telescope with F/10 still turns into F/6.7. The exposure time will be more than halved!
♦ An illuminated image field of 29 mm allows using all camera sensors up to APS-C format.

Adapter recommendations:

With the long working distance, adaptation of all common cameras, no matter whether CCD or DSLR, is possible without any problems. Some examples of applications:

♦ DSLR camera - adaption via M48: TSVF230 and then the matching adapter from M48 to the camera, like the SKM48-EOS for connecting a Canon EOS

♦ CCD cameras via T2 connection: two adapters are possible for reducing the M48 thread to T2:

TSFA2 - adapter to T2 with 38.2 mm length. This is used for bridging optical path.

TSM48-T2 - a short adapter with only 3.5 mm length. This is applied if accessories like off-axis guider and filter wheels should be used.
